To calculate height from a photo we need references and horizontal lines. In this image the rooftops in the background give an idea. The ridge of the house with a gable and red roof seems to be a bit higher than the camera. The house seems to be 3 floors - 9 m high. If the ground level is 3 m above sea level the camera should be around 10-12 m up in the air. As I don´t know the place I can be misled by angles and sizes. If the woo says 5,5 m, it´s wrong. If you say 20 m I wouldn´t buy that either.

Does anyone know how to prevent woo 2 from missing jumps besides landing hard? If you land on board and ride away but sink a bit or splash a bit does this effect it? If you have a jump that is a lot higher than the rest are these dropped as suspicious? I had a mediocre day around 5m jumps but one that was much much higher with very long hangtime around 10m plus but it doesnt show. How can I prevent this? Was extremely disappointing obviously as it was a clear personal record breaker but data shows nothing about it.

Interesting. I don't mind so much but that is a big difference between WOO and Xensr.. I ended up with both WOO2 and Xensr(1) and in my case the Xensr quite clearly indicates lower jumps than the WOO. Although I might have to upgrade the Xensr software (almost every month??) and I'm only comparing max hight here, not individual jumps, so not really scientific. But consistent over various sessions.
